Issey Miyake's IGO is a 20 ml "cap" (above left) that doubles as a travel spray. You can buy it separately, or you can buy it packaged with a 60 ml ISTAY bottle, which it then sits on top of (above right). Shown in Nectar d'Issey (which I assume is the same as L'Eau d'Issey Pure Nectar de Parfum, but who can say). Here is the brand's explanation, via Hudson's Bay in Canada, where they are $45 CAD and $138 CAD respectively, and where you'll also find the same set up in L'Eau d'Issey and L'Eau d'Issey Pour Homme:
IGO innovation: Innovative IGO does the double so you can use your scent at any time: IGO cap: travel-friendly, lightweight, unbreakable, the fragrance bottle is ready to go. Able to hold 20 ml of perfume, the IGO cap is a mini format ideal for travel. It can be carried independently in a bag so you can spritz your scent whenever you like.
ISTAY bottle: statuesque, elegant, iconic; a bottle to leave at home so you can come back to your archetypal fragrance when you return from travel.
And here is the matching video spot, which ought to make it all clear but perhaps does not quite accomplish that goal?
